| EE-digger:
TheSteve will probably chime in with better info but I don't think there is an easy method of identifying the parts that need to be swapped. I believe other efforts started with the 100MHz model. Also, keep in mind that 500MHz units I've looked at actually had a bandwidth around 600 to 625 MHz. I believe I've seen that the 1GHz scope has more of a brick wall above 1GHz (whereas the lower BW scopes keep going and going, albeit with loss of amplitude.) Just an FYI. |

Would that substantially reduce the number of components that need to be replaced to get to 1 GHz? --- End quote --- Did you read this topic? Literally in first post by OP there is a link to 500 MHz conversion by Memset where it is explained. https://www.eevblog.com/forum/testgear/keysight-3000t-scope-1-ghz-hardware-upgrade-mod/msg1245159/#msg1245159 500 MHz conversion is substantially easier. Sorry my memory serves me badly... That particular conversion was 3000A, not 3000T to 500MHz. |
| TheSteve:
The 500 MHz mod for the T series should be roughly the same as the A series however I don't think anyone has ever actually done it to verify 100% the exact components that need to be changed. And yes, it would be much simpler compared to the 1 GHz mod. |
